In this paper we investigate the distribution of PPs related to external arguments (agent, causer, instrument, causing event) in Greek. We argue that their distribution supports an analysis, according to which agentive/instrument and causer PPs are licensed by distinct functional heads, respectively. We argue against a conceivable alternative analysis, which links agentivity and causation to the prepositions themselves. We furthermore identify a particular type of Voice head in Greek anticausative realised by non-active Voice morphology.
